d2f9f8e094 lavr: correct the documentation for the ff_audio_resample() return value 2012-11-27 16:49:18 -05:00

7f534d11ed lavr: do not pass sample count as a parameter to ff_audio_convert() 
It will always be the number of samples in the input buffer, so just use that
directly instead of passing it as a separate parameter.

7a9e65acee x86: lavr: fix stack allocation for 7 and 8 channel downmixing on x86-32 
Fixes crashes on Win32 and stack overruns on x86-32 in general.

02738792c5 lavr: fix the decision for writing directly to the output buffer 
If there are any samples remaining in the output fifo from previous conversion
calls, we have to output those samples first instead of doing direct output
of the current samples.

04581c8c77 x86: yasm: Use complete source path for macro helper %includes 
This is more consistent with the way we handle C #includes and
it simplifies the build system.

10e645e9cb lavr: handle clipping in the float to s32 conversion 
We cannot clip to INT_MAX because that value cannot be exactly
represented by a float value and ends up overflowing during conversion
anyway. We need to use a slightly smaller float value, which ends up
with slightly inaccurate results for samples which clip or nearly clip,
but it is close enough. Using doubles as intermediates in the conversion
would be more accurate, but it takes about twice as much time.

parameter is not used, but the code is clearer if they match.
